Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal engineering construction technology, specifically to a rapid hoisting device for concrete drainage pipes. Background Technology
[0002] In the construction of municipal roads, flood control and drainage projects, the laying of concrete drainage pipes is a crucial step. Concrete drainage pipes are typically heavy, bulky, and require high precision in their connections; therefore, the quality of their hoisting and installation directly affects the overall construction efficiency and the safety of their subsequent use.
[0003] Currently, traditional methods for hoisting concrete drainage pipes mainly fall into two categories: one is to directly tie the pipe with steel wire ropes for hoisting; the other is to hoist it by inserting supports into the inside of both ends of the concrete pipe. However, both methods have obvious drawbacks in practical applications.
[0004] When using wire ropes for hoisting, multiple people are required to coordinate the binding operation, which is not only labor-intensive but also results in extremely poor pipeline stability during hoisting. Due to the unstable friction between the wire rope and the pipeline surface, the pipeline is prone to rotation, swaying, or even slipping in the air, posing serious safety hazards. Furthermore, the pipeline's attitude in the air is difficult to control, leading to significant deviations in the pipe end position during connection, requiring repeated adjustments and greatly impacting the construction progress.
[0005] While using supports inserted into both ends of the pipe for hoisting reduces pipe rotation to some extent, the limited contact area between the supports and the pipe's inner wall can easily lead to excessive localized stress on the pipe, causing damage. More importantly, this method makes it difficult to ensure axial alignment during hoisting, easily causing installation misalignment and resulting in low pipe joint precision, hindering rapid and accurate connection. In municipal road construction, each section of reinforced concrete pipe needs to be joined end-to-end, and the joints must be treated to form a whole. Installation misalignment increases the difficulty of joint treatment and may even affect the pipe's sealing performance and structural stability.
[0006] In addition, the existing solution of "a concrete pipe hoisting device" has improved the hoisting structure to some extent, but it still has problems such as the inability to easily adjust the pipe joint spacing and slow correction response speed, making it difficult to meet the needs of efficient construction in large-scale municipal engineering projects.
[0007] Therefore, the inventors have proposed a rapid hoisting device for concrete drainage pipes. Utility Model Content
[0008] The purpose of this utility model is to provide a rapid hoisting device for concrete drainage pipes, so as to solve the problems of poor hoisting stability, low installation accuracy, large safety hazards, and high labor intensity in the existing concrete drainage pipe hoisting methods.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0010] A rapid hoisting device for concrete drainage pipes, characterized in that it comprises: welded I-beams, load-bearing steel wire ropes, safety steel wire ropes, and correction steel wire ropes;
[0011] The welded I-beam includes a first welded I-beam component, a second welded I-beam component, and a third welded I-beam component. The first end of the first welded I-beam component is connected to the first end of the second welded I-beam component, and the second end of the second welded I-beam component is connected to the first end of the third welded I-beam component. The first and third welded I-beam components are arranged opposite to each other, and the second welded I-beam component is disposed between the first and third welded I-beam components. The welded I-beam is concave in shape.
[0012] The first end of the stressed steel wire rope is fixedly connected to the second end of the first welded I-beam component, and the second end of the stressed steel wire rope is detachably connected to the lifting hook.
[0013] The first end of the correction wire rope is fixedly connected to the end face of the first welded I-beam component away from the second welded I-beam component, and the second end of the correction wire rope is detachably connected to the hoisting hook.
[0014] The first end of the safety wire rope is fixedly connected to the end face of the first welded I-beam component away from the second welded I-beam component, and the second end of the safety wire rope is used for detachable connection to the lifting hook.
[0015] Furthermore, the first welded I-beam component includes a channel steel and a steel plate, wherein the steel plate is welded to the groove opening of the channel steel to form a columnar hollow.
[0016] Furthermore, it also includes fasteners disposed on the outer surface of the groove point between the first welded I-beam component and the second welded I-beam component for welding support.
[0017] Furthermore, the load-bearing capacity of the tension wire rope and the safety wire rope shall not be less than 50kN, and the material shall be high-strength alloy steel cable.
[0018] Furthermore, the welded I-beam has a cross-section of 150mm × 200mm and a span of 80% of the pipe length.
[0019] The beneficial effects of this utility model are:
[0020] This utility model achieves integrated hoisting and alignment through the coordinated design of three steel wire ropes: a load-bearing rope, an insurance rope, and an alignment correction rope. This solves the problem of traditional devices being unable to adjust angles synchronously. It requires no multiple people; a single person can operate it, reducing labor intensity, significantly minimizing material damage, and increasing construction efficiency by over 30%. Compared to existing solutions, it adds a real-time alignment correction function, improving docking accuracy to within ±5mm. A dual safety mechanism (primarily the load-bearing steel wire rope, with a backup insurance steel wire rope), combined with an adjustable alignment correction structure, ensures safety while achieving rapid docking.

Figure 1 , Figure 2 and Figure 4 As shown, the structure includes a welded I-beam 4, a load-bearing wire rope 1, a safety wire rope 2, and a guiding wire rope 3.

The first end of the first welded I-beam component 41 is connected to the first end of the second welded I-beam component 42, and the second end of the second welded I-beam component 42 is connected to the first end of the third welded I-beam component 43. The first welded I-beam component 41 and the third welded I-beam component 43 are arranged opposite to each other, and the second welded I-beam component 42 is disposed between the first welded I-beam component 41 and the third welded I-beam component 43. The welded I-beams are concave in shape; the first end of the load-bearing wire rope 1 is fixedly connected to the second end of the first welded I-beam component 41, and the second end of the load-bearing wire rope 1 is detachably connected to the lifting hook; the first end of the correction wire rope 3 is fixedly connected to the end face of the first end of the first welded I-beam component 41 away from the end face of the second welded I-beam component 42, and the second end of the correction wire rope 3 is detachably connected to the lifting hook; the first end of the safety wire rope 2 is fixedly connected to the end face of the first end of the first welded I-beam component 41 away from the end face of the second welded I-beam component 42, and the second end of the safety wire rope 2 is detachably connected to the lifting hook.
